[0032] As attached Figure 1-Figure 2 As shown, this embodiment provides a trampoline, comprising:

[0033] Jump cloth 10;

[0034] The trampoline frame 20 is arranged around the trampoline cloth 10. Springs (not shown in the figure) are evenly arranged between the trampoline frame 20 and the trampoline cloth 10. A protective ring 30 is provided above the springs. In this embodiment, the trampoline frame is rectangular.

[0035] At least one inner connecting ring 40 is disposed between the spring and the protective ring 30 . The inner connecting ring 40 is connected to the trampoline frame 20 via a first connecting member 50 . The first connecting members 50 are evenly distributed along the circumference of the inner connecting ring 40 . In this embodiment, there are two rectangular, concentrically arranged inner connecting rings 40 .

[0036] The inner connecting ring 40 is made of elastic material, and the first connecting member 50 is made of rigid material. In this embodiment, Figure 2 As shown, the inner connecting ring is an elastic rope, the first connecting member 50 is a rigid connecting rod, and the inner connecting ring 40 is in a tensioned state under the pulling force of multiple first connecting members 50. When a user jumps on the jumping cloth 10, the jumping cloth 10 deforms and moves downward, and the spring and protective ring 30 also deform accordingly. The first connecting member 40 tilts toward the center of the jumping cloth and moves downward, and the inner connecting ring 40 also moves downward and elastically contracts synchronously. When the jumping cloth 10 returns upward, the spring and protective ring 30 also return upward, the first connecting member 40 also returns in the opposite direction, and the inner connecting ring 40 also returns to the tensioned state. During the entire movement, the inner connecting ring 40 and the first connecting member 50 are always located between the spring and protective ring 30, isolating the protective ring 30 from the spring.

[0037] In this embodiment, the two inner connecting rings 40 are located between the trampoline frame 20 and the edge of the jumping cloth 10, and are also located above the spring and below the protective ring 30. The area of ​​the rectangle formed by the two inner connecting rings 40 is smaller than the area of ​​the outer ring of the protective ring 30, and larger than the area of ​​the inner ring of the protective ring 30. Without affecting the deformation of the jumping cloth 10, the inner connecting ring 40 and the first connecting member 50 isolate the protective ring 30 and the spring to reduce noise.

[0038] In this embodiment, the outermost inner connecting ring 40 adjacent to the trampoline frame 20 is connected to the trampoline frame 20 through a first connecting member 50 and a second connecting member 51 (not shown in the figure), and the inner connecting ring 40 located on the inner side is also connected to the trampoline frame 30 through a first connecting member 50 and a second connecting member 51. Figure 2 As shown, one end of the first connecting member 50 is connected to the trampoline frame 20, and the other end is connected to the second connecting member 51. The other end of the second connecting member 51 is fixed to the inner connecting ring 40. In this embodiment, the first connecting member 50 is a rigid connecting rod, and the second connecting member 51 is an inelastic connecting rope. The second connecting member 51 is located between the inner connecting ring 40 and the outermost inner connecting ring 40.

[0039] In order to evenly isolate the spring and the protective ring between the inner connecting ring 40 and the first connecting member 50 and the second connecting member 51, in this embodiment, connecting diagonal rods 21 are provided on the inner side of the four top corners of the trampoline frame 20. The connecting diagonal rods 21 and the top corners form a triangle. Mounting holes 22 are evenly provided on the trampoline frame 20 and the connecting diagonal rods 21, and one end of the first connecting member 50 is fixed in the mounting hole 22.

[0040] When exercising on the jump cloth, the jump cloth moves downward, the spring also moves downward a certain distance, the protective ring also moves downward, and the first connecting member 50 and the second connecting member 51 are pressurized and tilted downward along the center direction of the jump cloth. Since the first connecting member 50 and the second connecting member 51 are made of rigid material, the inner connecting ring 40 contracts to adapt to the deformation when it tilts, and moves downward at the same time. Then, the inner connecting ring 40, the first connecting member 50, and the second connecting member 51 can always isolate the spring and the protective ring to reduce noise. At the same time, during use, the gas generated under the jump cloth can be smoothly discharged from the gap between the first connecting member 50, the second connecting member 51, and the inner connecting ring 40, providing a better user experience.

[0041] like Figure 3 As shown, in another embodiment of the present application, there are two inner connecting rings 40, both of which are rigid rod-shaped structures. The two inner connecting rings 40 are connected by an elastic first connecting member 50. When the jump cloth 10 of this embodiment moves up and down, the first connecting member 50 undergoes elastic stretching and recovery deformation, and the inner connecting ring 40 moves up and down accordingly, and cooperates with the first connecting member 40 to isolate the protective ring 30 and the spring to reduce noise.

[0042] like Figure 4 As shown, in another embodiment of the present application, there is one inner connecting ring 40 , and the inner connecting ring 40 is connected to the trampoline frame 20 via a first connecting member. The inner connecting ring 40 is a rigid rod-shaped structure, and the first connecting member 50 is a spring.

[0043] In other embodiments of the present application, the trampoline frame 20 may be a circle, a square, or other polygonal or irregular shape.

[0044] In this technical solution, the protective ring and the spring are isolated by the inner connecting ring and the first connecting member, thereby avoiding direct contact between the spring and the protective ring and reducing noise;

[0045] At the same time, the inner connecting ring and the first connecting piece are both linear structures with good air permeability, which facilitates the discharge of gas generated under the trampoline during use; the cost is low and the installation is convenient.

[0046] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0047] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
